Ground Truth Solutions analysed survey data collected by the Argentinian Red Cross (ARCS) in early 2023, covering questions around trust as part of the Trust Index project.
The sampling employed a convenient sampling approach focused on large parts of the country in Argentina. The coverage overall is 96% of the country, when looking at inhabitants at the province level.
According to the provided information, the survey was mainly conducted at ARCS-organised events, which can be seen in the GPS coordinates, which indicate many local clusters and focused mainly on cities.
Overall, such sampling approach ensures familiarity with the ARCS, but also comes with the danger of biasing results, in particular social-desirability bias.
